Are Hidden 'Junk Fees' at Checkout Legal?

Not always, and often no. Advertising one price and then tacking on mandatory "service," "processing," or "convenience" fees at checkout can violate the Federal Trade Commission Act's ban on unfair or deceptive practices, and a growing number of states now require businesses to show the full, all-in price up front. The legality depends on whether the fee was disclosed clearly and early enough, whether it's truly optional, and which state's law applies.

The federal baseline: deceptive pricing is illegal

Section 5 of the FTC Act prohibits "unfair or deceptive acts or practices" in commerce. For decades, the Federal Trade Commission has treated a specific pricing tactic called drip pricing as a form of deception under this law. Drip pricing is when a business advertises only part of a product's price and reveals additional mandatory charges later in the buying process, drip by drip, until the customer reaches checkout and sees a much higher total than the number that first caught their eye.

The core legal problem isn't that a business charges extra fees. Businesses are generally free to set prices however they want. The problem is when the advertised price creates a false impression of what the customer will actually pay, and the truth only comes out after the customer has already invested time, entered payment information, or feels too far along to back out. That gap between the advertised price and the real price is what regulators target.

In 2024, the FTC finalized a nationwide rule commonly known as the "Junk Fees Rule" or the Rule on Unfair or Deceptive Fees, aimed squarely at live-event tickets and short-term lodging (hotels, vacation rentals, and similar bookings). That rule requires those businesses to disclose the total price, including mandatory fees, prominently and before a consumer is asked to pay, and it bans misleading fee names that misrepresent what the fee is actually for. Litigation and rulemaking in this area have continued to evolve, so the exact scope and status of any single FTC rule can shift; what has stayed constant is the FTC's underlying Section 5 authority to pursue deceptive pricing across virtually any industry, not just ticketing and lodging.

The FTC has brought enforcement actions and obtained settlements against companies in industries well beyond tickets and hotels, including subscription services, food delivery, and rental listing platforms, for burying mandatory fees or making them look optional when they weren't. The agency's consistent position: if a fee is mandatory, it has to be baked into the price the consumer sees first, not sprung on them at the last screen.

What counts as a deceptive fee versus a legitimate one

Not every add-on fee is illegal. Fees tend to be defensible when they are:

• Disclosed before the consumer commits, ideally alongside the initial advertised price, not revealed for the first time on the final payment screen.
• Accurately named for what they actually cover, rather than dressed up in vague language like "convenience fee" when the charge is really extra profit margin unrelated to any specific service.
• Genuinely optional, if marketed as optional. A fee for expedited shipping you can decline is different from a mandatory fee falsely framed as a choice.

Fees become legally risky when they are mandatory but hidden until deep into checkout, when the fee name misrepresents its purpose (calling a pure profit markup a "government-mandated fee," for example), or when the business advertises a price in marketing or search results that a typical consumer could never actually pay once the fees are added.

State law: where the real teeth often are

This is an area where state law frequently goes further than federal law, and it varies significantly by state. Some states have passed or are considering "all-in pricing" or "honest pricing" laws that require the first price a business displays, whether online, in an app, or in an advertisement, to include all mandatory fees except for government-imposed taxes and, in some cases, actual final shipping charges disclosed before payment.

California is a leading example. California's Honest Pricing Law (enacted as SB 478, amending the state's Unfair Competition Law and Consumers Legal Remedies Act) generally requires businesses advertising a price for goods or services to display the total price a consumer must pay, inclusive of all mandatory fees or charges other than government taxes and certain reasonable shipping costs. Businesses can still list a tax and a genuinely optional gratuity separately, but they generally cannot hide mandatory resort fees, service fees, or processing fees and reveal them only at the end.

Other states have their own consumer protection statutes, often called "mini-FTC Acts" or Unfair and Deceptive Acts and Practices (UDAP) laws, that state Attorneys General use to pursue hidden-fee complaints even without a specific junk-fees statute on the books. Because these laws differ state to state in scope, remedies, and whether they allow individual consumers to sue directly, you'll want to check your own state's consumer protection statute or your state Attorney General's consumer guidance rather than assume a rule from one state applies where you live. Some states also regulate specific industries more tightly, such as rules aimed at hotel resort fees, rental application fees, or ticket resale fees, that don't exist in neighboring states.

Who enforces these rules

Three types of enforcers matter here, and understanding the difference helps you know where to complain:

• The Federal Trade Commission enforces the FTC Act's deception standard nationwide and can pursue rulemaking, investigations, and lawsuits against companies engaged in drip pricing or mislabeled fees, particularly in industries covered by its specific rules.
• The Consumer Financial Protection Bureau has authority over deceptive practices tied to financial products and consumer financial services, so hidden fees connected to bank accounts, credit products, or similar financial services may also fall within its jurisdiction.
• State Attorneys General enforce their own state consumer protection and UDAP statutes, and many have consumer complaint portals specifically for hidden-fee and pricing complaints. State-level enforcement is often faster and more accessible for an individual consumer than a federal complaint.

What to do if you're hit with a surprise fee at checkout

You have real, practical options, whether or not a specific statute covers your situation:

• Screenshot everything. Capture the initial advertised price, every step of the checkout flow, and the final total before you pay. If the fee appeared only after you'd already entered payment details, that timing matters and is easy to lose track of once the transaction is done.
• Save the receipt and any confirmation email showing the itemized charges, including the exact name given to the disputed fee.
• Ask the business directly for an itemized breakdown and a refund of the undisclosed portion. Many companies will refund a disputed fee to avoid a chargeback or complaint, especially for a first-time ask made politely and promptly.
• Dispute the charge with your card issuer if the business won't cooperate. Card networks and issuing banks have chargeback processes for billing disputes, and a documented pattern of hidden fees is often persuasive.
• File a complaint with the FTC through its consumer complaint system, and separately with your state Attorney General's consumer protection office. Even if neither agency resolves your individual case, complaints build the pattern-of-conduct evidence regulators use to open broader investigations.
• Check whether your state has an all-in pricing or UDAP law that lets you bring your own claim, sometimes with statutory damages, attorney's fees, or the ability to join a class action if the fee affected many consumers the same way.

Keep an eye on timing. Complaint portals and card-dispute windows often have practical time limits, sometimes measured in weeks after the charge posts, so don't sit on a hidden-fee problem for months before acting.

When it's worth talking to a lawyer

Most individual hidden-fee disputes are worth trying to resolve through a refund request, a card dispute, or an agency complaint before spending money on legal help. It's worth a consultation with a consumer protection attorney if the fee was large relative to the purchase, if the same undisclosed fee appears to have hit many other customers (a possible class action), or if a business is retaliating against you for disputing a charge, such as threatening your account or reporting a false debt. Many consumer protection attorneys offer free initial consultations and only get paid if you recover money, so a quick conversation costs little to explore.

The bigger trend: all-in pricing is becoming the norm

The direction of travel, both federally and at the state level, is toward requiring "all-in" pricing, meaning the first number a consumer sees should be the real number they'll actually pay, aside from taxes and truly optional add-ons. Ticketing platforms, hotel and short-term rental sites, and a growing list of other industries have already shifted their checkout flows in response to FTC rulemaking and state laws like California's. Expect more states to adopt similar requirements over time, and expect enforcement in industries beyond tickets and lodging to keep expanding as regulators apply the same deceptive-pricing logic to new sectors like food delivery, event booking, and subscription services.

Know the law

Your core consumer protections come from the FTC and the CFPB at the federal level, plus your state Attorney General.

Key federal laws:

• FTC Act § 5 (unfair or deceptive practices), 15 U.S.C. § 45
• Fair Credit Reporting Act (FCRA), 15 U.S.C. § 1681 et seq.

Where to get help or file a complaint:

• Report fraud to the FTC
• Consumer Financial Protection Bureau (CFPB) — submit a complaint

Your state matters too. Federal law is the floor — your state sets the statute of limitations on debt, garnishment and exemption limits, payday and repossession rules, and has its own Attorney General and consumer-protection laws. Always check your state’s rules. This is general legal information, not legal advice.
